Overview
Most SOAP use cases can and should be handled using native Appian features like Integration Objects. This plug-in specifically is suited for handling SOAP services with SOAP and Base64 attachments
Key Features & Functionality
The Advanced Call Web Service provides support for the following:
We encountered a structural limitation in the Advanced Call Web Service (Endpoint) plugin when handling SOAP responses with attachments via Axis2/MIME parsing. The plugin exposes attachments only as temporary Appian document objects (<fileattachtemp>), but these files lose any metadata required to reliably identify or match them with the corresponding attachment information from the SOAP XML (e.g. <NroAttachment>, <IdDoc>, or <fileName>). Since Appian does not preserve a stable order of MIME parts and no correlation keys are provided in the response, it is technically impossible to deterministically associate the extracted temporary files with their original metadata. This makes attachment mapping unreliable and prevents safe processing of SOAP attachments in real-world integrations.
